[PATCH net v2 1/3] net: dsa: rzn1-a5psw: enable management frames for CPU port

[alexis . lothore]

From: Clément Léger <clement.leger@xxxxxxxxxxx>

Currently, management frame were discarded before reaching the CPU port due
to a misconfiguration of the MGMT_CONFIG register. Enable them by setting
the correct value in this register in order to correctly receive management
frame and handle STP.
